I generally keep screen brightness lowest.While laptop is on battery if I do not use mouse or keyboard for some time (I do not exactly know this time interval, maybe 20 second) brightness increases to some level between highest and lowest. Also if I use mouse or keyboard after this happens brightness becomes highest.This is very annoying. What is the solution if there is any?

Aditya M P over 10 yearsI noticed that unchecking the
Dim screen to save power
option, and then setting a custom brightness, seemed to solve this issue.

Dmitry Koroliov almost 10 yearsin 14.04 there is no such a setting like
idle-dim-ac
and others. It seems to be a bug in Ubuntu, because the settingDim screen to save power
should be responsible for this, but it does not affect this behavior -
mikewhatever almost 10 yearsHi, and thanks for the comment. As you've noticed, Ubuntu evolves, and things change. The original question was not about 14.04, as it's been posted some three months before the development of Trusty got started.
